I have a Dell Latitude laptop, Windows XP Pro Sp3, with Avast, Zonealarm, Malwarebytes, Spybot Search and Destroy, Spywareblaster.
The pointer function became problematic a few months ago when it would jump into the corners and try to stay there. After doing some reading it seemed that the touchpad may have been be wearing out, and the mechanical interface inside could have been the problem. I solved this by keeping the laptop tilted when I use it, and have had no further problems with a jumping mouse.
Last week a new problem with the pointer began. After the computer has been on for a few minutes it makes pale dotted rectangles when I move it around on my basic screen. In the recycle bin it creates pale blue rectangles. When I am using a program it tends to highlight things. I am not always able to get rid of the highlighted stuff and just have to close the window. It feels like the mouse and the left click button are not always communicating. If I move the pointer over a desktop icon it is likely to drag it across the screen for awhile.
So far I have run all my security programs with nothing found, including the Avast boot scan.
I would love to fix this problem myself if possible. Let me know if you need further info!
